Abstract
The invention relates to a generator of the harmonic of laser light destined in particular for application in the equipment for spectrometric measurements carried out with the laser technique. The substance of the invention is to shorten many times the optic route in the generator of the harmonic of laser light by the replacement of the system of elements of a zero dispersion by at least one dispersive element of a great dispersion, in particular by a rutile prism, combined with the system reversing the polarization surface by 90.degree., in partricular with a 90.degree. polarization rotator or a half-wave plate.
